Question

5. Frictional force, on an object
moving in a fluid, depends on its
1.Shape of the object
2.Motion of the object
3.Nature of the fluid
4.All of these​

Answer 1

Answer is option (d) All of these.

Answer 2

4. All of these

The speed of the object moving through a fluid affects the amount of friction acting against the motion of the object. More the speed, more is the friction. If the object is broad, it gives more area for the friction to act on. Thus, a streamlined body structure helps to cut through the fluid and reduce friction. Also, the nature of the fluid affects friction.
